I special _ mounting of casts 10 I CAD/CAM 3_2015 _Discussion Based on the records and examination, the following were determined: Class I occlusion, 20% overbite, 0/2 mm overjet, canine guidance and evidence of a parafunctional habit. The diagnosis included mildly discoloured anterior composites and bruxism. The patient was pre- sented with several treatment plans, ranging from preoperative whitening followed by mini- mally invasive composite replacement to an- terior porcelain veneers. An occlusal splint was also recommended. Although she was unde- cided on the treatment modality, the records obtained with Max provided valuable informa- tion for the clinician, the patient and third-party insurance. If treatment is to proceed, important information on occlusion, guidance and aes- thetic determinants will be accurately conveyed to the laboratory. Utilisation of the clinical component of Max provided a very simple approach to capturing the clinical data. The process was straight- forward, the anatomical guides proved very useful and the record of occlusion provided additional crucial information that is often omitted. There were no software glitches or errors during operation. The patient also found the process extremely quick and comfort- able. Max has several safeguards to guarantee optimisation. There is a sensor to ensure it is properly positioned when taking the photo- graph of the patient. If it is not properly posi- tioned, image capture will not occur. Calibration may be required in order to ensure that the sensor is correctly set. This is achieved by posi- tioning the tablet vertically in the stand and then pressing the “calibrate sensor” button. Thesensitivityofthepositioningsensormayalso be adjusted with the “adjust sensitivity” button. If the clinician has become frustrated and must take the image immediately, there is a “force capture” button that will override the sensor and take an image. Future development may consider the option of saving the image in STL format. This would enable various output options and use with other digital image and design software. _Conclusion Max provides a novel and innovative ap- proach to the mounting of casts using a tablet, reinforcing the anatomical and aesthetic con- siderations when establishing a simulated pa- tient case. The accurately mounted tangible casts provide substantial information for diag- nostic and treatment planning, beneficial to dental students, new graduates and experienced clinicians. Compared with traditional approaches, such as facebow transfer, Max provides an easy, efficient and accurate method for clinical in- formation acquisition that has benefits for both the clinician and patient. Its ease of use would perhaps encourage clinicians to consider uti- lising Max as a vehicle for obtaining crucial clinical data. This would enable greater overall communication, improved success in prosthesis fabrication, and a more satisfying experience for the patient and clinician._ Editorial note: A list of references is available from the publisher.
